Ok, so I got the flywheel for the r150. Now it's time to build a balancing jig to match it to the original benz. The bellhousing will need to be cut back about 1" and I will make a new mounting flange drilled for the mercedes bolt pattern. The flange will be welded to the trimmed bellhousing. The bolt holes for the toyota flywheel are a slightly smaller spacing and the center hole is about 3mm too small. I need to find a machine shop to make these corrections before I balance it. So if anyone knows of a machinist in the Portland area that would do this let me know. I am also looking for the r150 transmission.
